Hypothesis of strong chaos and anomalous diffusion in coupled symplectic maps
Eduardo G. Altmann, Holger Kantz
We investigate the high dimensional Hamiltonian chaotic dynamics in coupled area-preserving maps. We show the existence of an enhanced trapping regime caused by trajectories pe…
Precursors of extreme increments
Sarah Hallerberg, Eduardo G. Altmann, Detlef Holstein +1
We investigate precursors and predictability of extreme increments in a time series. The events we are focusing on consist in large increments within successive time steps. We are…
Nontwist non-Hamiltonian systems
E. G. Altmann, G. Cristadoro, D. Pazó
We show that the nontwist phenomena previously observed in Hamiltonian systems exist also in time-reversible non-Hamiltonian systems. In particular, we study the two standard colli…
Stickiness in Hamiltonian systems: from sharply divided to hierarchical phase space
Eduardo G. Altmann, Adilson E. Motter, Holger Kantz
We investigate the dynamics of chaotic trajectories in simple yet physically important Hamiltonian systems with non-hierarchical borders between regular and chaotic regions with po…
